But more likely, the seeds escape through some openings at the end of the fruit. Notice they mouth-like openings at the end of the fruit. These close up if the fruit gets wet during the rain, but they open ujp when the weather is dry and windy. This suggests that the seeds are dispersed by wind. The fruit of Darlingtonia is like a shaker--only a few seeds escape at a time, because the mouth-like openings are small. This benefits the plant, because dispersing seeds over a period of weeks means that the seeds will reach more places. Also, more seeds are dispersed on a windy day, because more seeds sift out through the openings. If seeds of a plant are wind-dispersed, a mechanism like this that disperses more seeds on a windier day is better, because the seeds will be carried farther, and Darlingtonia seeds could reach distant places where it could grow well.
